Air Transportable Loran System

The Air Transportable Loran-C System (ATLS) has
been developed in order to provide the Coast Guard with the
capability to rapidly get a Loran-C station back into operation
after it has been partially or completely destroyed through natural
disaster or enemy action. The system also provides the capability of
rapidly installing a single station or a new Loran-C chain. Each
station was developed by converting Coast Guard furnished Loran
equipment, communications, power generation, and fuel storage and
transfer equipment. and other long-lead-time procurement items to an
air-transportable rapid-assembly and configuration. This was done
primarily by installing the equipment in shelters and utilizing
removable interconnections between the shelters for the electronic,
electrical, and mechanical systems.

Each ATLS facility consists of eightteen
shelters.

Stations established utilizing the ATLS package stored in Hawthorne, Nevada.
